The Periglacial Landscape of Mars: Insight into the \u27Decameter-scale Rimmed Depressions\u27 in Utopia Planitia [PDF]

, 2018
Currently, Mars appears to be in a ‘frozen’ and ‘dry’ state, with the clear majority of the planet’s surface maintaining year-round sub-zero temperatures.

Repeated and Long‐Lasting Fault Activation on Amazonian Mars as Demonstrated by Tectonically Induced Landslides

Geophysical Research Letters, Volume 51, Issue 9, 16 May 2024.
Abstract We identify and analyze a large shortening structure (surface expression of a thrust fault) in western Arabia Terra, Mars, exhibiting recent, repeated, and long‐lasting tectonic activity. Where the fault system deforms Marsabit crater rim, four landslides with differing degradation states extend onto the crater floor.

Widespread Excess Ice in Arcadia Planitia, Mars [PDF]

, 2015
The distribution of subsurface water ice on Mars is a key constraint on past climate, while the volumetric concentration of buried ice (pore-filling versus excess) provides information about the process that led to its deposition. We investigate the subsurface of Arcadia Planitia by measuring the depth of terraces in simple impact craters and mapping a

An ice-rich flow origin for the banded terrain in the Hellas basin, Mars [PDF]

, 2015
The interior of Hellas Basin displays a complex landscape and a variety of geomorphological domains. One of these domains, the enigmatic banded terrain covers much of the northwestern part of the basin.

Reconciling Mars InSight Results, Geoid, and Melt Evolution With 3D Spherical Models of Convection

Journal of Geophysical Research: Planets, Volume 129, Issue 5, May 2024.
Abstract We investigate the geodynamic and melting history of Mars using 3D spherical shell models of mantle convection, constrained by the recent InSight mission results. The Martian mantle must have produced sufficient melt to emplace the Tharsis rise by the end of the Noachian–requiring on the order of 1–3 × 109 km3 of melt after accounting for ...

Capillary Processes in Extraterrestrial Contexts

Journal of Geophysical Research: Planets, Volume 129, Issue 5, May 2024.
Abstract The Earth is no longer the only known celestial body containing one or more liquid phases. The Cassini spacecraft has discovered seas of hydrocarbons at the surface of Titan, while a series of corroborating evidences argue in favor of the existence of an aqueous ocean beneath the icy crust of several moons.

Mars Orbiter Laser Altimeter: Experiment summary after the first year of global mapping of Mars [PDF]

, 2001
The Mars Orbiter Laser Altimeter (MOLA), an instrument on the Mars Global Surveyor spacecraft, has measured the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of volatile and dust clouds.

Thermally Driven Winds on Mars: A Review and a Slope Effect Numerical Study

Journal of Geophysical Research: Planets, Volume 129, Issue 4, April 2024.
Abstract Regional and local thermally driven winds are planetary boundary layer phenomena frequently observed on Mars over sloping and flat regions, when diurnal surface temperature variations are significant and large‐scale winds are sufficiently weak. In particular, slope flows are prevalent in many areas on Mars, where they can reach high speeds and

Constraints on Lateral Variations of Martian Crustal Thickness From Seismological and Gravity Field Measurements

Geophysical Research Letters, Volume 51, Issue 4, 28 February 2024.
Abstract Using body wave arrival times from 31 seismic events recorded on Mars by the InSight mission, combined with topography and gravity field modeling, we constrained lateral variations of crustal thickness through a Bayesian inversion approach. The parameterization of the seismic structure relies on quantities that influence the thermochemical ...
